Guys,
As of yesterday I've managed to pick up the above fault code. If I clear the code the car runs fine for a few miles before popping back up and running in limp mode.
After much searching and reading I've tracked it down to 3 possible issues...MAF, Lambda probes or Boost/VAC leak.
So today I spent most of the day replacing boost/vac pipes, some of which were completely shot.
Whilst I was there I also removed the MAF and an N75 and cleaned them thoroughly with IPA/Isoprop.
Whilst I was there I also disconnected the battery.
I refitted the MAF, N75, double checked all the hoses, reconnected the battery and performed a TBA before taking the car out for a spin.
A few miles later the car is back in limp mode with the same fault logged.
Some further reading lead me to check block 031 and 032 with VAG-COM (http://www.uk-mkivs.net/forums/391473/ShowPost.aspx)
Here are my findings....

Car is fine until lambda 2 hits +10.
Next log is after the code is cleared...
http://www.seatcupra.net/IbizaR/LOG-002-031-032_Run2.xls
Max MAF reading is/was 149.97 g/s, limp mode soon followed along with the fault code....
Control Module Part Number: 6K0 906 032 AB
Component and/or Version: 1.8L20VTCUPRA R 0001
Software Coding: 11500
Work Shop Code: WSC 78133
1 Faults Found:
17536 - Fuel Trim: Bank 1 (Mult): System too Lean
P1128 - 35-00 - -
As as an aside I decided to clear the fault again and unplug the MAF, took the car for a quick spin and it went like stink with every run. No errors were logged apart from the MAF signal too low (obviously).
Car spec is as listed in my signature....
Any ideas guys?
Cheers,
Marts
